HTML5 and CSS3 are more than just buzzwords - they're the foundation for today's web applications. This book gets you up to speed on the HTML5 elements and CSS3 features you can use right now in your current projects, with backwards compatible solutions that ensure that you don't leave users of older browsers behind. This new edition covers even more new features, including CSS animations, IndexedDB, and client-side validations. HTML5 and CSS3 power today's web applications, with semantic markup, better forms, native multimedia, animations, and powerful APIs. You'll get hands-on with all the new features with practical example projects, and find what you need quickly with this book's modular structure. "Falling Back" sections show you how to create solutions for older browsers, and "The Future" sections at the end of each chapter get you excited about the possibilities when features mature.
